The Moody Blues are one of my very favorite bands, however, Nights in White Satin is one of my least favorite songs of theirs because it was over-played. It seemed like most radio stations thought that that was their only hit and played it over and over and over without delving into their other numerous great songs. However, I listened to the link above and Matt Cardle has breathed new life into the song and I fell in love with it all over again as if hearing it for the first time. This guy's good! The passion with which he sang it gave me goosebumps.
As for Roberta Flack's song - Wow! This guy is not only good, but great! And watching the judges reaction brought tears to my eyes. Thanks for sharing these links.
May the tail of the elephant, never have to swat the flies from your face.
